Product Description
Among the many components of a steam turbine, gaskets are an important component mainly used to fill the gaps between two or more components to prevent leakage.
Stainless steel toothed gasket is a type of gasket made of stainless steel material, which is characterized by using a toothed structure to increase the sealing effect. This type of gasket is usually used in situations where high sealing performance is required, because stainless steel has good corrosion resistance, high temperature resistance, and mechanical strength, and can adapt to the complex temperature and pressure environment in steam turbines.
The commonly used special toothed gasket for steam turbines include 15CrMoA, 35CRMOA, 40CrMoV-5, 45Cr1MoV, 0Cr18Ni9, 1Cr11Co3W3NiMoVNbNB, 1Cr18Ni9Ti, 20Cr1Mo1VNbTiB, 20Cr1Mo1VTiB, 25Cr2MoVA, 2Cr11Mo1NiWVNbN, and 2Cr12NiMo1W.
The manufacturing of Toothed gasket requires precise process control to ensure their precise dimensions and meet high quality standards. Quality control is crucial throughout the entire manufacturing process. By using various inspection techniques such as size measurement, metallographic microscopy, ultrasonic testing, etc., ensure that each bolt meets the specification requirements.

Product Features of Toothed gasket
1. It has excellent high-temperature resistance and can work stably for a long time in high-temperature environments.
2. High strength, able to withstand high pressure and high temperature force loads during turbine operation.
3. It has good anti loosening performance and can maintain stable fastening force in vibration environments.
Wide Application of Toothed gasket
Toothed gasket are widely used in various key parts of steam turbines, including the following aspects:
1. Static sealing parts: In the static sealing parts of the steam turbine, such as the installation flange of the static blade, the connection between the bearing cover and the axle box, and the static shell components, toothed gaskets can be used to prevent medium leakage.
2. Dynamic sealing parts: In some cases, toothed gaskets can also be used for dynamic sealing parts, such as sealing between rotors and stationary components, but this usually requires special toothed design to meet the requirements of rotating components.
3. Steam leakage prevention: In the steam pipelines and valves of the steam turbine, toothed gaskets can be used to prevent steam leakage and improve the steam tightness of the system.
4. Exhaust system: In the exhaust system, toothed gaskets can be used to prevent hot gas leakage and improve exhaust efficiency.
When selecting and using stainless steel toothed gaskets, it is necessary to determine the most suitable gasket type and size based on the specific working conditions and medium characteristics of each part of the steam turbine.
